每次 sudo apt 升级后，Ubuntu Server Wifi 连接都会失败

我的 Ubuntu 18.04.3 服务器有问题。该服务器通过 wifi 连接到我的家庭网络，并具有静态 IP 地址。它大多数时候运行正常，但我反复遇到以下问题：

  1. 我 ssh 进入机器，发现有许多可用的升级
  2. 我安装升级
  3. 我重新启动
  4. 我无法再通过 ssh 访问该机器
  5. 我进入机器并登录。欢迎屏幕上没有显示 IP 地址
  6. 我重启了一下。一切又恢复正常了。

我查看了成功和不成功启动（成功建立连接）的日志。日志大致相似，但我发现成功启动的日志结尾为：

wpa_supplicant[760]: wlp1s0: WPA: Group rekeying completed with 40:0d:10:ad:70:2f [GTK=TKIP]

启动失败似乎会短暂地建立连接，但随后会出现：

wpa_supplicant[763]: nl80211: deinit ifname=p2p-dev-wlp1s0 disabled_11b_rates=0
systemd[1]: Stopping WPA supplicant for netplan wlp1s0...
etc...

没有明确的错误，只有关于结束连接的消息。有人知道为什么会发生这种情况吗？是否可以在重启后立即运行脚本来查看是否已建立连接，如果没有，则尝试获取连接？

编辑20191222：

自从第一次问这个问题以来，我现在有两个 cron 作业在周日早上运行。第一个执行更新并重新启动。第二个，一个小时后，再次重新启动。这似乎让我在使用服务器时一直在线。检查日志后，服务器似乎在第一次重新启动后有时在线，在第二次重新启动后始终在线。

/etc/netplan 中只有一个 .yaml 文件。它看起来应该类似于此...

network:
  version: 2
  renderer: networkd
  wifis:
    wlp1s0:
      addresses: [192.168.0.66/24] # don't use the same IP address as enp3s0
      gateway4: 192.168.0.1
      nameservers:
        addresses: [8.8.8.8,8.8.4.4]
      access-points:
        "99PinkGins":
          password: "###############"
  ethernets:
    enp3s0:
      dhcp4: true
      optional: true

sudo netplan --debug generate

sudo netplan apply

reboot
